Application led November 3, 1908. Serial No. 460,816.

To all 'whom 'it 'may concern:

Be it known thatrI, ALBERT CHAMPION, of Flint, `in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Insulators and Conductors forvElectric Currents, of whichthe following is a specification.

This invention has relation to insulators for conductors of electric currents and to a combination therewith of one `or more conductorsin addition to a main conductor.

In other words, the invention'consists of -a conduit or tube composed of non-conductive material, in the wall of'which one or more conductors are embedded and which is adapted to serve as a container for another con A chamber.

The chief object of .the invention is to provide a holder for 'a plurality of conducas nearlyaspossible an absolute protection to the conductors, both electrically and physically. As is generally known, currents of' great voltage jump :from one conductor to another if. the conductors are suiciently closeto each other, protected by a material ha property.'

a 'great degree of insulatin ective holder containing especially adapted for use with h' h tension 1 currents, and, secondly, to means or inclosset'fo'i'th in lthe following specification and pointed out in the claims.-

Referring to the drawings, forming a part of this 'SpecicatiOm--Fgure 1 is an elevation of one form `of an insulating holder adapted for a pluralityof conductors. Fig. 2 is .an-elevation'v thereof 'at an angle of 90 from the aforesaidelevation. v Fig. 3 isa plan view and'dia am of-electric wirin of 'an internal com ustion motor to whic theinvention is adapted. 'Fi'g. 4 is a section on the line 4 4 of Fig. 3. Fi 5 is a longitudinal section of one end of t e insulator. Fig.' 6 is a. 'section on line 6-6 of l l Fig. .1. Fig/I is a similar section with the Specicatio-n o! Letters Patent.

addition of conductors and an external covering.

The same reference characters indicate the same parts wherever they occur.

The drawings illustrate the invention as applied to an internal combustion motor, but yit is by no means limited to this use or arrangement. In this connection, however, Figs electrical system f a four-cylinder motor of the aforesaid type. The holder may be of any desired roportions 'and cross sectional 65. shape As s own, the holder is lcylindrical, having an internal chamber 11 open-at the ends.l The holder is composed of any hi hly insulated material such as glass, ,porce ain,

., y. o l The chamber lllis intended as a conduit for a separate removable conductor hereinafter described, andthe wall\or shell of the holder is of sufficient thickness to contain y several individual conducto s. These .oon- 15 ductors may installed in various ways, that shown being in the for tof strips inlaid in the exteriory surface of the shell. -For this pu 'f 15 are f orme ose, ooves 12, 13,14 and in tg; shell and afterward so filled with the vconducting1 material.' l The ooves may be formed eit er in the molding of the shell or by a cutting process. If the shell be made of glass, the grooves may be formedv by the chemical action of iluorin on such parts-.as are intendedto' be eaten away thereby. For setting the conductors in the` grooves,

various methods' may be' emploed.' In this instance, in which a lass s el is shown, a 9c successful, method o installing the-.conductors is tocover the shell with wax except along'the lines of the ooves, and to tl ien submit it to a precipitation of gas containing nitrate of silver. n this way a thin layer of silver, is deposited in the grooves m which it adheres to lthe glass. By then removing the wax covering and immersing the silver nlaid shell in an electro-plating bath, .the `silver maybe covered toany desired thickness with metal, preferably copper. this way, conductors 20 may be laid in the grooves and maybe inclosed by a coating or covering 16 of insulating material such as land 2 illustrate a tubular holder-or vconduit 10 adapted to be employed in the varnish. See Fig. 7.A In'thisform of the invention, the conductors are preferably left eontainedin the wall or shell of a conduit composed of insulating material.

By way of describing the particular use to which this form of the invention is adapted, reference is now made to Figs. 3, 4 and 5, in which the cylinders of a motor are indicated at 25.-.'1Th'e shell 10 is here contained in a casing 26 mounted in any desired manner near the tops ofthe cylinders as shown. The casing is composed of non-conducting material such as vulcanized .ubberand has end caps 27 of similar material. The caps are here confinediby a rod 28 somewhat longer than the casing and extending there- .through as Well as through the caps themselves. The ends of the rod are screwthi-adelinav are provided with cimpmg nuts 29 vfor `holding the capsand the rod in place. lAccording to this arrangement, the rod.28"is utilized as a conductorin an electric circuit for producing sparks in the cylinders- 25." The current .in the circuitl is thereforefof high voltage and is distributed successivelyto spark plugs 31, 32, 33 and 34 through a rotary distributer' 35 and other means. The current, generated inthe'sec- Wire 39" similarly wires 41, 42, 43 'and 44 to binding ondary winding 36 ofa transformer, passes through av wire 37 to oneendv ofthe rod 28 towh-ich the wire may be bound by a nut 38.

The other end of the rod is connected to a rotary arm of the distributer by means of a The stationary contactsiof. the distributor are connected by' posts 40 mountedin the casing 26. Connection is made Vbetween each binding post 40 and one set of terminals 21, 22, 23 and 24 by means of helical springs shownin Fig. 4.

`In addition to the bin 51,52, 53 NSPW' ebases of the switches. are' connected -to the'other set and 24 by helical ductor for engaging against their seats.

posts, the casisfprovided with spht switches 1 and ,iwhich m adapted@ ftivelythe plugs 31, 32, 33 and 34.

th oneside of the 36 grounded onthe cylinders 25, the circuit is made successively through 4the conductors 20 contained in the wall of the shell 10, but the conductors are here so farseparated and so thoroughly insulated as to be ca. able of transmitting a,current of'high vo tage without liability of leakage.

The rod 28, which.' a feeder for the conductors 20, is aorded equal protection Vagainst leakage and liability of detailgev ue ment by external interference. The

of this arrangement is especially apparent in connection with automobiles and powerboats driven by motors of this type.- Having thus ex lained the 'nature of my said invention, an described a way of con-` structing and using the same, although without attempting to set forth all of the forms in which itmay be made or all of the mod of its use, vwhat I claim is:

1. The combination. with a tube of insulating material having conductors embedded in its wall, of a casin for said'tube, said casing having an o mng for theinsertion and removal ofy sai tube, means for covering said openin and a conductor extending through said tu and through said covering means and -connected to said cover means whereby said covering means isl astened against said casing. f

2. The combination with a tube of insulating material having conductors embedded in its wall, of a'casin for said tube, said cas-A ing being open at th ends, covers for the openings in. the ends' of said casing, a conductor extending through said tube and through said covers, and means for connectingsaid conductor and said covers whereby said covers are fastened said casing.

3. The combination with a tube of insulat- Ving material having conductors embedded inv its wall,`of a 'cas' ing being Open at openin in the' ends of said said' covers ing adapted to confine saidtube in one position, a conductor extending through said covers, and means on said'conand holding said covers for said tube, said casth ends, covers -for the through 'said tube out of contact therewith' and f '10s
